The SMB3315 Satellite Modem Board is supported on multiple platforms
to cover the widest range of markets and applications. The modem
shares a wide range of key features and can be easily mixed in a single
satellite network on either Evolution, Velocity or Dialog platform. The
modem is extremely flexible as it can leverage several different return
waveform technologies across mutiple platforms*: ATDMA, MF-TDMA,
high-rate SCPC and Mx-DMA MRC which seamlessly combines MF-
TDMA flexibility with on-demand variable bandwidth allocation of SCPC
while guaranteeing the highest efficiency and availability. The SMB3315
also supports wideband operations up to 500 Msps in the forward
channel, enabling service providers to set-up any type and size of
network on HTS/VTS.
The SMB3315 Board is suitable for integration into highly compact
COTM terminals for the government and defense, broadcast and
mobility markets. It offers unprecedented performance in a modem
board, supports a broad array of mobility capabilities and is fully
equipped to operate on HTS spot beams satellites.
The SMB3315 is also available in a desktop form factor, the MDM3315.
